ADOLPH HILLE, OF HOPKINSVILLE, KENTUCKY.

SCREW-PRESS.

SPECIFICATION forming part of Letters Patent No. 391,146, dated October 16, 1888.

Application filed March 9.6, 1888. Serial No. 26 ,555. (No model.)

To aZZ whom it may concern.-

Be it known that I, ADOLPH HILLE, acitizen of the United States, residing at Hopkinsville, in the county of Christian and State of Kentucky, have invented certain new and useful Improvements in Screwlresses; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention has for its objects to provide an improved device for prizing or pressing loose tobacco or other products of a similar nature into tubs, hogsheads, or other receptacles, to pack the same for transportation or storage; and it consists, essentially, in a pcculiar arrangement of nuts, which work upon the leading or master screw by which the compression is effected in connection with a lock-lever, whereby either the upper or lower nut may be locked upon the screw, so as to turn the same in either direction, or all of the nuts may be made to work freely on the screw to permit the device to be moved longitudinally thereon, as more fully hereinafter specilied. These objects I attain by the means illustrated in the accompanying drawings, in which-- Figure 1 represents a perspective view of a press showing my invention applied thereto. Fig. 2 is a side elevation showing the screw and the nuts located thereon. Fig. 3 represents a similar view showing the intermediate nut locked against the upper nut. Fig. 4 is a similar view showing the intermediate nut locked against the lower nut. Fig. 5 is a side elevation showing the nuts and locklever in position to turn the screw in one di rection; Fig. 6, a similar view showing the parts arranged to turn the screw in the opposite direction; and Fig. 7, views of the nuts and rock-lever detached, showing the upper and lower faces of the same.

The letter A indicates a base constructed of timber or other suitable material, and B side supports mounted upon the said base at the sides thereof, having a cross-head O, at their upper ends securely bolted therein, so as to bear the strain of the leading or master screw D, the said screw being arranged to work vertically through an internally-threaded bushing, E, at the center of the cross-head. The baseis provided with a platform, F, which supports the tub or cask G.

The letter H indicates a follower which fits in the tub or cask, and which is provided with a bearing or step, I, in which the lower end of the screw fits and is adapted to turn freely.

The letter K indicates a threaded nut, and L M two other threaded nuts, the whole of which are arranged to work on the screw D, as shown. The intermediate nut is provided with cogteeth N on its periphery or a portion thereof, and the nuts L M with lugs I m at one side. Between the lugs is pivoted a lever, P, which is provided with acogged seg- 7o ment, It, at its inner end, which intergears with the cogs on the nut K, so that it may be turned in either direction, so as to cause it to bind against the upper or lower nut, L or M, at will, and lock the same to the screw in order to turn said screw in either direction.

The letter S indicates a pin, which may be passed through openings in the lugs of the upper and lower nuts, to limit the movement of the lever as it swings upon its pivot.

When the lever is in a position radial to the nuts, they move freely on the screw, but when in a position tangentially thereto at either side theintermediate nut will be made to bind against either the upper or lower nut, so as to permit the screw to be turned in the desired direction.

Having thus described myinventiou, what I claim, and desire to secure by Letters Patent, 1s

1. The combination, with the leading or master screw of a press, of the threaded nuts arranged thereon, the intermediate nut being provided with cogged teeth on a portion of its periphery, and the operating-lever having a cogged segment intergearing with the cogs of the intermediate nut, whereby the same may be made to bind against the upper or lower nut to turn the screw in the desired direction, substantially as specified.

, 2. The combination, with the upper and In testimony whereof I afiix my signature in lower nuts having lateral lugs, of the intermepresence of two witnesses. diate cogged nut, the segmentally-cogged lever fulcrumed between said lugs and intergearing v ADOLPH HILLE. 5 with the cogs on the intermediate nut, and the detachable pin, whereby the movement of the Witnesses: lever may be limited in either direction, sub- A. ROSENBERG, stantially as and for the purpose specified. O. M. ARMSTRONG.
